Slow leaking tire... then fast

[sleblanc63]

I have been the luckiest driver I know in regards to tires. Been driving for 35 years and might have a had two flats on the side of the road and only one blowout. So I'm really not up on tire damage cause and affect.

 

Last night I parked my truck at 6:30. Didn't move it until 6:00 this morning. When I got in it, TPMS said RR tire low @ 19 psi. Drove a few miles to air, aired up, no problem. Inspected the tire found no objects in it. Got to work and all good. Three hours later someone comes in my office and says my tire is flat. So parked for 12 hours 15 lbs down. Then parked for three hours and 28 lbs down

 

I found a slit/ puncture wound just at the top corner of the tread and sidewall about an inch long. No scrub or jagged damage.

 

Is it possible I hit a piece of metal and got a very clean slice that barely went through and the way it was parked last night it was pinched closed and then the way I parked it at the office it was pulled open?

 

Or did my hot girlfriends crazy ex poke my tire early this morning?

Anything is possible but I wouldn't blame the ex because you had a low tire warning in the same tire the day before. It's likely that the tire had a problem and it got worse in some way. Maybe whatever punctured the tire worked itself deeper when you drove the truck or it fell out allowing more air to leak out.

NoMoRage - hope the tire wasn't new, any slit on puncture on the side wall can't be patched.

All this happened last night/ this morning. Headed to the tire shop after work. It's right on the corner of the tread but on the side of the tire... Discount tire says it's 50/50 and will require internal inspection. I'm thinking it's junk.

The slice will have gotten worse when the tire flexed as you drove on it.
